Airport security is now tighter than before.
So are shipping ports.
Banks are under a microscope, it is no longer easy for terrorists to move money using numbered accounts as it was before, the same applies to heavy ordnance and the nefarious material they use to make bombs. Its why terrorists are using street level assault weapons to commit these acts.
What Kenya (and the world) now needs is a brand new way of mopping up small arms and ammunition from the street, from the public, and ensuring there is no fresh supply.
Then build a wall from the lowermost Indian Lamu ocean end, to the far end upto Mandera; militarized border bases every 100 kilometers each with patrol and assault helicopters, bases too on the UG border side, with aggressive patrolling,..I hear Ethiopian troops first shoot border trespassers then consider questions afterwards, kushikwa Ethiopia bila papers is no joke, utaona cha mtema kuni. Start stringing people from trees for corruption in the immigration department, harsh prison sentences, no sacred cows so that no one will fathom selling a kenyan passport or id card to a terrorist for money or a sleazy drug dealer from Congo.
Hata kama itakula half our GDP, I would really love to see a 5 year plan of something like this.
We make it impossible for terrorists to arrive as freely as they have been doing in the past, from resupplying, slipping in and out at will, then we eliminate the ones within our borders systematically.
No genius. No long winded intelligence thingamajiggery, just very straightforward policy, procedural and legal steps. Al Capone, for all his conniving and wily ways, was brought down by tax legislation.
